In the current research, a comprehensive experimental study has been performed to explore the properties of Epoxy matrix hybrid composite reinforced by Nano Al2O3and graphite. The mixing process was done by homogenizer to achieve consistent scattering of the filler particles into the matrix. Mechanical tests, such as Tensile and Flexural Bending test were conducted to evaluate the performance of Epoxy hybrid composite. Experimental investigations were done on several specimens of epoxy composite by varying the weight percentages of the graphite filler from 1 to 5 at different wt % of Nano Al2O3and also the results were compared among themselves for different wt % samples. The mechanical characteristics such as Tensile and Flexural Bending of epoxy hybrid composite material can be appreciably enchased by the introduction of Nano Al2O3, graphite particles.
This article examines the terms \"production system\", \"cyber-physical system\" and \"cyber-physical production system\". The research is a scientific search for the similarities and differences between them.\nThrough systematic analysis and synthesis of the main content and structural characteristics of the terms \"production system\", \"cyber-physical system\" and \"cyber-physical production system\" their definitions are upgraded and refined.\nCriteria are highlighted according to which similarities and differences are synthesized, and through analysis similarities and differences are synthesized, conditioned by the definitions of the studied concepts.
Introduction: The Roux-en-Y gastric bypass (RYGB) is, currently, the most performed technique in Brazil. Suture wires are classified according to their degradation properties. Objective: To analyze the influence on the size of the gastrojejunal anastomosis performed in Roux-en-Y gastric bypass surgery, as well as the main complications with the use of absorbable or inabsorbable wire. Methods: This study followed a prospective and randomized clinical trial, initially with 40 participants, with only 37 participants being duly selected, 19 of whom underwent gastrojejunostomy closure with an absorbable (Abs) polydioxanone suture (PDS II®) and 18 with the inabsorbable (Inb) ETHIBOND®. Statistical analysis was performed using the ANOVA and logistic regression tools (p<0.05 significant). Results: General complications and Upper Digestive Endoscopy (UDE) were less frequent at the end of 12 months in both groups. At the end of twelve months, the number of complications of the Inb thread decreased considerably, while the number of complications of the Abs thread showed an increase in other complications, including marginal ulcer and intrusive thread. Despite this, there was no significant difference between groups in terms of total weight loss. There was no statistically significant difference between the final values of the anastomotic diameter. The percentage of weight loss over the 12 months was 33.77 ± 6.97% for the Inb group and 36.10 ± 4.89% for the Abs group (p<0.05). Conclusion: Both suture wires (Inb and Abs) presented similar complications and did not present significant differences between the values of weight, gastrojejunal anastomosis, and pouch.
